    <p>The 'instant' volume changes approximately every 50ms; the 'slow' volume approximates the average volume over
        about a second.</p>
    <p>Note that you will not hear your own voice; use the <a href="../audio">local audio rendering demo</a> for that.
    </p>
    <p>The <code>audioContext</code>, <code>stream</code> and <code>soundMeter</code> variables are in global scope, so
        you can inspect them from the console.</p>
